Special Purpose Simulation (SPS) is a proven principle that can lead to the effective transfer of simulation knowledge to the construction industry. Three separate industry experiments have led to the identification of a set of requirements that construction SPS tools should adhere to in order to be successful. This set of requirements was then used in the… (More)

This paper discusses the process of building a special purpose simulation environment. By making the environment specific for a given industry many advantages are gained including wider acceptance and use in practical settings. Special purpose simulation tools help bring simulation to the desks of construction engineers who have little or no experience with… (More)

Simulation studies are well suited for the analysis of earth moving operations for many reasons. First, projects generally involve some form of resource interactions where certain equipment must obtain certain resources before proceeding. Second, task durations are highly empirical and are thus suited for stochastic modeling. And third, projects are… (More)

Presents concepts and implementations for automated construction simulation modeling for aggregate crushing plant operations (CRUISER) and for earthmoving operations (AP2-EARTH). In the automated modeling environment, the user can specify a real-world construction system: its physical components, required resources and other system information. A simulation… (More)

Traditional methods of dealing with variability in simulation input data are mainly stochastic. This is most often the best method to use if the factors affecting the variation or the nature of the relationships between the factors and the outputs can not be easily identified. Artificial Neural Networks have the ability to learn complex relationships… (More)
